Fill in the following fields:

  1. Name. The system name that the recipient will not see.

  2. Sender. Sender ID that was added to the system. Users will see it as the sender of the message.

  3. Message type. You can use a few types for different purposes:

  • Transactional message — contains only text.

  • Promotional message — can contain text, an image, and a button. Providers charge higher prices for promotional messages than for transactional messages.

Before sending, Viber should approve the transactional message template. Messages with unapproved text will not be delivered.

It can include:

  • Up to 1,000 symbols;

  • Emoji and special characters;

  • Clickable links;

  • Name — display text on a button.

How to Send SMS to Contacts Who Don’t Use Viber

If you send a bulk campaign to all contacts with a phone number and don’t know who of them uses Viber, create a multichannel workflow and add an SMS block as a backup.

The workflow will include the following blocks:

  • Start;
  • Viber. In Message, select the corresponding Viber message;
  • Timer.

We recommend setting the timer for not less than 30 minutes because the minimum time to live of the Viber messages is 30 minutes. After it, all contacts without Viber accounts get to Errors and will be sent SMS. The more time you specify in Timer, the more contacts with the Viber account will receive Viber messages.


If you set less than 30 minutes, the contact may receive both a Viber message and SMS.

  • Delivered;
  • SMS. In Message, select the corresponding Viber message;
  • End.

Workflow example


To see reports on bulk and triggered Viber messages, go to Campaigns > Reports and select Viber.
